A Mammoth Spring man was sentenced to the Arkansas Department of Correction after being convicted of three counts of rape Nov. 9.
Michael Seibert, 36, was originally charged with 20 counts of class Y felony rape involving a minor female in September 2005.
In an interview conducted at the Fulton County Sheriff's Office the day prior to his arrest, Seibert admitted to engaging in sexual activity with a 12-year-old female from October 2004 through August 2005, according to special agent Jeff Stone and Crimes Against Children investigator Jeanette Cooper, both with the Arkansas State Police.
According to the official police report, Seibert initially told authorities he was not sure how many times he had assaulted the female or how long the abuse had taken place. However, Seibert confirmed the victim's report that he had assaulted her over 20 times throughout the course of her summer vacation when he told investigators, "the girl would know."
In Thursday's Fulton County Circuit Court Seibert reached a plea agreement with prosecutors. The court agreed to drop 17 of the rape charges, and Seibert plead guilty to the remaining three counts.
Prior to the plea agreement, Seibert faced the possibility of life in prison on each count. With his current conviction, Seibert is set to serve 30 years in the state facility, and he will have to register as a convicted sex offender at the time of his release.
